Feline Hyperthyroidism Prognosis

The prognosis for feline hyperthyroidism is not all bad. When treated early and effectively, many cats can fully recover and have normal thyroid activity restored.

Many pet owners are unaware of the condition and may not know what to expect. If your cat was recently diagnosed with feline hyperthyroidism, you may be wondering about his or her prognosis.

What is it?

When a cat’s thyroid gland creates too much of the thyroid hormone, this is known as feline hyperthyroidism. It affects a cat’s metabolism and can result in:

Weight loss

Increased appetite

Increased activity & restlessness

Matted, greasy or poor coat

Fast heart rate

Increased water drinking

Vomiting

Diarrhea

Difficulty breathing

Weakness

If left untreated, the condition can be fatal. Thankfully, there are a few different treatment options, including radioactive iodine therapy, surgical treatment, and medication. Your cat’s prognosis will vary depending on what type of treatment it receives.

Effective Treatment for Feline Hyperthyroidism

The prognosis for feline hyperthyroidism is best when treated with radioactive iodine therapy. This treatment involves:

An injection of radioactive iodine, absorbed quickly into the cat’s bloodstream

The iodine will go to work destroying abnormal thyroid tissue

It will leave surrounding tissues and parathyroid glands untouched

It won’t cause any additional damage

After your cat is injected with radioactive iodine, he or she will need to remain in a treatment facility for a few days to be monitored until radiation levels are acceptable. These treatments can only be performed at specially licensed facilities.
If your cat is experiencing symptoms of feline hyperthyroidism, please contact your veterinarian immediately. The prognosis for feline hyperthyroidism is better the earlier it is caught and treated.
